<br>Hi: <br><br>My device has 2 endpoints (of transfer type Interrupt), one is in (0x81 EP 1 IN) and the other is out (0x02 EP 2 OUT).<br><br>I issued hid_interrupt_write(hid, 0x81, MY_PACKETS, PACK_LEN, 10000);<br>and it returned:
<br><br> could not claim interface 0: Device or resource busy.<br><br>This is even though my HID has been opened and interface was created successfully.<br><br>I tried reading by hid_interrupt_read(hid, 0x02, myresults, 2, 10000);
<br>and it returned:<br> <br> error submitting URB: no such file or directory.<br><br>Did I do something wrong with these interrupt write/read requests?<br><br>Thanks<br><br>Mark<br><br>
